During the past three decades, much attention has been given to free-living nematodes and, in particular, to the species of the African continent. Despite the current absence of evidence for the existence of planktonic species, several conditions are suggested that could lead to intrusion of the planktonic habitat, e.g. turbulent shallow waters, high food densities and preadaptations such as swimming ability and negative geotaxis. A new and more practical ecological classification of the inland…

Global diversity of nematodes (Nematoda) in freshwater
TLDR
Recent discoveries show high nematode abundance and diversity in cryptic freshwater bodies, underground calcrete formations and stromatolite pools potentially with a high number of new taxa.
Nematode communities of Lake Tana and other inland water bodies of Ethiopia
TLDR
Free-living nematodes from littoral benthic sediments of four lakes, two rivers and a hot spring in Ethiopia are studied and variations with the considered environmental factors viz. site, water depth, sediment depth, median grain size and percentage of mud in the sediment are associated.
9 – NEMATODA AND NEMATOMORPHA
The biology and ecology of lotic nematodes
TLDR
Evidence such as the increased bacterial activity due to nematode grazing suggests that such interactions may be significant, and methods for fixation, extracting and preparing nematodes for identification are described.

Distribution and feeding of the predatory nematode Anatonchus dolichurus (Mononchoidea) in the Dokka delta (Norway) and its impact on the benthic meiofauna
  • K. Prejs
  • Environmental Science, Biology
  • 1993
TLDR
A dense population of a large, semiaquatic, predatory nematode Anatonchus dolichurus was found in the delta of the River Dokka, Norway, the first time it has been reported in surface fresh waters.
SUSPENSION OF MARINE NEMATODES IN A TURBULENT TIDAL CREEK: SPECIES PATTERNS
TLDR
Nematodes had a mean abundance of hundreds per m3 in an estuarine creek and were dominated by three species of Metachromadora which comprised 57% of the suspended nematodes.
Effects of biological disturbance by Monoporeia affinis (Amphipoda) on small-scale migration of marine nematodes in low-energy soft sediments
TLDR
This is the first paper ever that investigates the influence of macrofauna on nematode short-range migration, and finds that Migration of nematodes over short distances is likely to be slow in the absence of strong physical forces.
An assessment of animal species diversity in continental waters
There is a need for monitoring the status and trends of freshwater biodiversity in order to quantify the impacts of human actions on freshwater systems and to improve freshwater biodiversity…
An assessment of animal species diversity in continental waters
TLDR
The purpose is to complete existing projects by providing quantitative estimates of species number for all freshwater groups on each continent and/or major eco-regions by compiling existing data from literature, web sites and museum collections and contacting scientific experts of each group to provide a ‘to the best of their knowledge, estimates ofspecies numbers’.

Nematode associations in the Exe estuary
TLDR
A study of the distribution of nematodes in the Exe estuary was planned to cover as wide a spectrum of physical and chemical conditions as possible, and a large proportion of the species found were new British records, and some new to science.
The ecological importance of free-living soil nematodes with special reference to those of moorland soil.
TLDR
An attempt to investigate their food relations and to convert the results of numerical sampling into biomass and respiration estimates for a British moorland habitat is described.
Workshop on taxonomy and biogeography
TLDR
The species concept in Rotifers, as in many other animal groups, is applied by various investigations in a rather lax way; there is insufficient insight into the contribution of morphology to reproduce isolation, or to avoidance of interspecific competition.
Effect of temperature on life cycles of nematodes associated with the mangrove (Rhizophora mangle) detrital system
TLDR
The effect of temperature on the life history of various representatives of the meiofauna associated with decaying mangrove leaves was investigated, and the ability to complete a life cycle was inconsistent within the temperature range of 33° to 35°C.
Freshwater Nematodes From South Africa 5. Chronogaster Cobb, 1913
TLDR
The morphology of the genus Chronogaster Cobb, 1913 is discussed, and an emended diagnosis presented for the genus, and four new species are described from South Africa.
A bioenergetic study of a benthic nematode, Plectus palustris de man 1880, throughout its life cycle
TLDR
The allometric function, R-aWb, adequately describes the relationship of respiration and body weight only during the larval growth phase and for young females, while respiration rates of newly hatched larvae and mature females at maximal egg production have lower metabolic rates.
Three New Alaimus-Species (Nematoda: Alaimidae) From Mount Kenya 1)
TLDR
The arrangement of the anterior sense organs and the position of the oesophageal gland nuclei agree with the placing of the Alaimidae near the Oxystominidae.
Species of the Genus Mylonchulus (Nematoda: Mononchidae) Occurring in Southern Africa
The following species are reported from a number of localities in Southern Africa: Mylonchulus lacustris (Cobb, 1915), M. montanus (Thorne, 1924) and M. sigmaturus (Cobb, 1917). Two new species are…
South African species of the genus Cobbonchus Andrassy, 1958 (Nematoda: Mononchidae).
TLDR
Four new species are described and illustrated of Cobbonchus eurystoma, which is distinguishable from other members of the genus by the shape of the stoma which is broad with small teeth, and C. ockerti, which resembles C. mauritianus (Williams) Clark but differs with regard to theshape of the tail, the position of the amphidial apertures and the presence of a single prodelphic ovary.
Species of Aphanolaimus (Nematoda, Araeolaimida) from Africa
TLDR
Examination by scanning electron microscopy revealed some interesting morphological characters, such as the structure of the amphideal fovea, extremely small mouth opening, cuticular striation, lateral field,cuticular pores and setae and male supplements in the new species A. louisae.
